IMIROVED MACHINE FOR IINISHING lTHE EDGE OFBOOT AND SHOE-SOLES @theSdgcmtle nient it in tips@ trttcts ttent nu making un n f tige sans.

TO ALL WHOM IT MAY GONCERN Be it known that I, CHARLES W. PALMER, ofLynn,'in the eountyvof Essex, and State of Massachusetts, have inventedan Improved Power-Machine for Finishing'the Edges of Boots and Shoes;and I do hereby declare that the following, taken in connection with thedrawings which accompany and form part of this specification, is adescription of my invention suiiicient to enable those skilled in theart to practise it.

For certain classes of boots and shoes the soles are cut to form, orsize and shape, by whole dies, or otherwise, so that they do not have tobe trimmed or out on the edges by hand-knives by the workmen.

For finishing the edges of such soles, hand-tools have heretofore beenemployed to give grooved edges of any desirable conformation, and thepolished surface required. The use of such-toolsrequires a great amountof muscular labor, consuming much time, and the object of my inventionis to lessen the labor and time required, besides effecting thefinishing of sole-edges in a superior manner.

In finishing solecdges as described, by hand, it has been generally thepractice to apply the hand-to0ls to the soles after they are secured 4inplace ou boots or shoes, though, more rarely, the nishing of the edg'eshas been donesupon the soles before they have been fastened to theuppers.

In making use of my machine, the edges of the soles are invariablyfinished by it before the soles are applied to the boots or shoes ofwhich they are to form a part.

The drawing represents an elevation of a machine embodying my invention.

a denotes a frame, having bearings at ZJ, in which a shaft, c, is madeto rotate rapidly, by means of a belt applied to the pulley d, xed onthe shaft between the bearings. On the end of the shaft is affixed acylinder, preferably of metal, into which are turned grooves of a widthcorresponding with the thickness of the solecdges to be finished, theedges of the grooves, or the flanges on the cylinder, forming guides orgauges, which prevent any sidewise movement of the soles submitted tothe action of the machine. On the bottom surfaces of these grooves maybe left small ridges, which are such in number and shape as to producein the sole-edges the grooved formation required for ornament. The sidesof the grooves or the flanges are preferably mede a little flaring, sothat the sole will enter the groove easily. A number of these groovedcylinders may be made to shift off and on the shaft, so that a largevariety of patterns-or groovings may be impressed on the edges of solesof various thicknesses.A

The finishing-operation is improved by heating the cylinder, which maybe done by a ilame appliedbeneath, the workman applying the soles to theupper part of the cylinder, rarely using that part which is below ahorizontal plane passing through its centre. The lcylinder may be madehollow, and steam may be introduced for the purpose of heating it.

The workman holds a solo in his hands, andintroduces it into the groove,which is of a width corresponding to the thickness of thc sole, andthen, pressing the sole upon the rapidly-revolving cylinder, moves thesole so that all portions of Vits edge receive the frictional Contactoffthc bottom surface of the groove, by whiehthe edge is smoothed,polished, and grooved, if grooving is required, and if the beads orillets'are made on'the bottom surface of the groeve.

On the other end of theshaft is shown a modification of my invention.Thev cylinder there shown is not formed with flanges; only thegrowing-fillets or heads are made on the cylinder, if desired.

The gauges or guides are made separate from the cylinder, and attachedto the frame by means of screws, the screw-holes in the gauges beingslotted, so that the gauges can be adjusted toward or from cach other totit Aany thickness of sole. A

I claim, for the purpose of nishing the edges of detatched soles, themachine constructed and operating 'substantially as described.

CIIAS. W. PALMER.
